[0068] In Figures 1 to 7In the illustrated embodiment, the front hood 1 further comprises a hinge reinforcement plate 11 and a latch mounting plate 12. The hinge reinforcement plate 11 and the latch mounting plate 12 are both assembled to the inner hood panel 20, the hinge reinforcement plate 11 is used to reinforce the fixed hinge, and the latch mounting plate 12 is used to mount the latch. In some embodiments, the material of the inner hood panel 20 and the outer hood panel 10 is carbon fiber. The material of the outer hood panel 10 and the inner hood panel 20 is selected to be carbon fiber material, which can balance light weight and strength to meet energy saving requirements. The hinge reinforcement plate 3 and the latch mounting plate 4 are sheet metal materials to ensure the rigidity of the mounting points of the hinge and the latch, and are bonded to the inner panel 2 of the front hood by epoxy structural adhesive, and are further installed and fastened by bolts and nuts. In some embodiments, the front hood 1 further comprises a bonding layer 13, which can be an epoxy structural adhesive, and is arranged between the outer hood panel 10 and the inner hood panel 20.

After the front hood 1 is closed, the front engine compartment is formed.

[0069] In Figures 1 to 7 In the illustrated embodiment, the inner hood panel 20 is partially recessed to form a flow guide surface 202 in the area of the heat dissipation channel. The flow guide surface 202 is located above the engine. A plurality of air guide holes 201 are arranged in different areas of the flow guide surface 202. By arranging the recessed flow guide surface 202, the inner hood panel 20 and the outer hood panel 10 have a certain space heat dissipation channel, which is beneficial to concentrated heat dissipation of the engine in the front engine compartment. Specifically, the flow guide surface 202 comprises a flow guide bottom surface 203 and a plurality of flow guide side surfaces 204 arranged on the circumferential side of the flow guide bottom surface 203, and a plurality of air guide holes 201 are arranged in the flow guide bottom surface 203 and / or the plurality of flow guide side surfaces 204. In some embodiments, the plurality of air guide holes 201 are arranged in the flow guide bottom surface 203. In other embodiments, the plurality of air guide holes 201 are arranged in the flow guide side surface 204. In the present embodiment, the plurality of air guide holes 201 are arranged in the flow guide bottom surface 203 and the flow guide side surface 204. Arranging the recessed flow guide surface 202 above the engine and arranging the plurality of air guide holes 201 in the flow guide bottom surface 203 and the flow guide side surface 204 is beneficial to concentrated heat dissipation of the engine in the front engine compartment, and realizes the heat dissipation requirement in the front engine compartment.

[0070] In Figures 1 to 7In the illustrated embodiment, the air guide holes 201 include first air guide holes 2011 and second air guide holes 2012. The first air guide holes 2011 are formed in the air guide bottom surface 203, and the second air guide holes 2012 are formed in the air guide side surface 204. The air guide bottom surface 203 has a larger contact area with the front compartment than the air guide side surface 204. The first air guide holes 2011 formed in the air guide bottom surface 203 serve as the main air guide holes.

[0071] In Figures 1 to 7 In the illustrated embodiment, the inner hood panel 20 includes an inner panel front end 20A and an inner panel rear end 20B arranged opposite to each other. The inner panel front end 20A is arranged closer to the head of the front compartment than the inner panel rear end 20B. The head of the front compartment can be the front of the vehicle. That is, the inner panel front end 20A is arranged closer to the front of the vehicle than the inner panel rear end 20B, and the inner panel rear end 20B is arranged closer to the driver's compartment of the vehicle than the inner panel front end 20A. In some embodiments, the air guide bottom surface 203 is arranged obliquely from the inner panel rear end 20B to the inner panel front end 20A, i.e., from the outer hood panel 10 to the inner hood panel 20. The air guide side surfaces 204 are arranged obliquely relative to the air guide bottom surface 203. That is, the air guide bottom surface 203 extends in two directions, not only from the driver's compartment to the front of the vehicle, but also from top to bottom, so that the air guide bottom surface 203 is arranged obliquely relative to the outer hood panel 10, and the air guide side surfaces 204 are arranged obliquely relative to the air guide bottom surface 203. The air guide bottom surface 203 and the air guide side surfaces 204 are arranged obliquely to maximize the areas of the corresponding first air guide holes 2011 and second air guide holes 2012, which facilitates the discharge of hot air in the front compartment and improves the heat dissipation effect.

[0072] In Figures 1 to 7In the illustrated embodiment, the flow guide side surface 204 is arranged obliquely relative to the flow guide bottom surface 203, from the edge of the flow guide bottom surface 203, extending from the inner side to the outer side of the flow guide bottom surface 203. That is, the flow guide side surface 204 is obliquely arranged from the edge of the flow guide bottom surface 203, expanding outwardly from the flow guide bottom surface 203. By obliquely arranging the flow guide side surface 204, the area of the second air guide hole 2012 can be increased, the flow guide effect is better, and heat dissipation is facilitated. In some embodiments, the angle between the flow guide side surface 204 and the flow guide bottom surface 203 is equal to or greater than 90°. In some embodiments, the angle of inclination between the flow guide side surface 204 and the flow guide bottom surface 203 is equal to 90°. In other embodiments, the angle of inclination between the flow guide side surface 204 and the flow guide bottom surface 203 is greater than 90°. In the present embodiment, the angle of inclination between the flow guide side surface 204 and the flow guide bottom surface 203 is greater than 90°, which on the one hand can reduce the difficulty of process forming, and on the other hand can increase the area of the second air guide hole 2012, facilitating heat dissipation and improving the heat dissipation effect.

[0073] In Figures 1 to 7 In the illustrated embodiment, the heat dissipation hole 101 and the plurality of air guide holes 201 are arranged staggered in the direction in which the inner panel rear end 20B extends toward the inner panel front end 20A, and the heat dissipation hole 101 is arranged closer to the inner panel rear end 20B relative to the plurality of air guide holes 201. That is, the heat dissipation hole 101 and the plurality of air guide holes 201 are arranged staggered in the direction in which the cockpit is toward the vehicle head, and the heat dissipation hole 101 is arranged closer to the cockpit relative to the plurality of air guide holes 201. Since the cold air passing through the front grille passes through the radiator, the heat of the radiator is taken away by the fan, and the hot air rises to the top of the cabin, and is guided out to the heat dissipation hole 101 of the outer panel 10 of the hood through the plurality of air guide holes 201 of the inner panel 20 of the hood. When the vehicle is running, the surface of the front hood 1 will generate negative pressure at the plurality of air guide holes 201 due to the Bernoulli principle, and the hot air is discharged through the heat dissipation hole 101 of the outer panel 10 of the hood by utilizing the negative pressure. Therefore, such arrangement is more conducive to heat dissipation.

[0074] In Figures 1 to 7 In the illustrated embodiment, the inner panel 20 of the hood includes a first connecting flange 205 and a second connecting flange 206 located on the side of the first connecting flange 205. The inner panel 20 of the hood is sealingly connected by the first connecting flange 205 and the second connecting flange 206. In the present embodiment, the outer panel 10 of the hood and the inner panel 20 of the hood are bonded by the epoxy structure of the bonding layer 13. The inner panel 20 of the hood and the outer panel 10 of the hood are sealingly bonded by the first connecting flange 205 and the second connecting flange 206 and the bonding layer 13, and have good sealing performance. The bonding layer 13 is arranged between the first connecting flange 205 and the second connecting flange 206, and the outer panel 10 of the hood and the inner panel 20 of the hood are connected by the bonding layer 13. The outer panel 10 of the hood and the inner panel 20 of the hood are fixedly connected by the bonding layer 13, and have better sealing performance.

[0075] In Figures 1 to 7In the shown embodiment, the heat dissipation channel is located in the area enclosed by the first connecting flange 205 and above the engine. That is, the heat dissipation channel is isolated from the area outside the first connecting flange 205 and inside the second connecting flange 206 in the area enclosed by the first connecting flange 205, and has good sealing performance, which is conducive to the discharge of hot air flow, and locating the heat dissipation channel above the engine is more conducive to concentrated heat dissipation of the engine, thereby meeting the heat dissipation requirement in the front engine compartment.

[0076] In Figures 1 to 7 In the shown embodiment, the heat dissipation channel is formed between the hood outer plate 10 and the hood inner plate 20, so that there is a gap between the hood outer plate 10 and the hood inner plate 20. The gap should not be too small or too large. If it is too small, it will limit the flow rate of hot air flow and affect the discharge of hot air flow. If it is too large, the space in the front hood 1 is limited. Therefore, in the present embodiment, the minimum gap of the heat dissipation channel is at least 22 mm. In this way, in the limited space of the front hood 1, it is conducive to the discharge of hot air.

[0077] In Figures 1 to 7 In the shown embodiment, the hood inner plate 20 includes a plurality of lightening holes 207, and the plurality of lightening holes 207 are arranged at intervals. The plurality of lightening holes 207 are symmetrically distributed along the central axis of the hood inner plate 20. In some embodiments, a part of the lightening holes 207 are located in the area enclosed by the first connecting flange 205 and on the side of the plurality of air holes 201 facing the vehicle head, so that the heat dissipation is not affected. Another part of the lightening holes 207 are located between the first connecting flange 205 and the second connecting flange 206, but not limited. By arranging the plurality of lightening holes 207, the weight of the hood inner plate 20 is reduced on the basis of meeting the rigidity of the hood inner plate 20, the cost is reduced, and the lightweight is achieved.

[0078] In Figures 1 to 7 In the shown embodiment, the hood inner plate 20 includes a plurality of weakening holes 208, and the plurality of weakening holes 208 are arranged at intervals and distributed on the peripheral side of the first connecting flange 205. The plurality of weakening holes 208 are arranged at the connection between the hood outer plate 10 and the hood inner plate 20. In this way, on the basis of ensuring the overall rigidity of the hood inner plate 20, the structure of the hood inner plate 20 is locally weakened, which not only achieves the effect of pedestrian protection and collision energy absorption, but also achieves the lightweight.

[0079] In the above scheme, the cold air passing through the radiator of the front grille of the vehicle is taken away by the fan, and the hot air rises to the top of the front cabin, and is guided out to the radiator holes 101 through the heat dissipation channels formed by the plurality of air guide holes 201 between the hood outer plate 10 and the hood inner plate 20. When the vehicle is running, the surface of the front hood 1 will generate negative pressure at the opening position due to the Bernoulli principle, and the hot air is discharged through the radiator holes of the hood outer plate 10.

[0080] Since the radiator holes 101 are provided on the hood outer plate 10, water from the outside may enter the front cabin from the radiator holes 101. Therefore, in the present embodiment, the front hood 1 further comprises a drainage device 30, which is mainly used to drain the water entering from the radiator holes 101. The water here is not limited, which may be rainwater on a rainy day, water entering from car washing, water from melting ice and snow in frost weather, glass water for washing glass, or other liquids, which are not limited in the present application.

[0081] The conventional front hood structure has a shaped hole on the surface, and no corresponding drainage structure is provided, so that the cabin cannot meet the waterproof requirement. Therefore, the present application provides a front cabin that meets the waterproof requirement on the basis of meeting the high-efficiency exhaust requirement.

[0082] Figure 8 As shown in Figure 1 The front hood 1 of the drainage device 30 is shown in the exploded view. Figure 9 As shown in Figure 1 The front hood 1 of the drainage device 30 is shown in the structure schematic view of the front view. Figure 10 As shown in Figure 1 The front hood 1 of the drainage device 30 is shown in the structure schematic view of the top view.

[0083] In combination with Figure 2 , Figure 6 , Figures 8 to 10 As shown, the front hood 1 further comprises a drainage device 30, which is located below the drainage hole 209. The drainage device 30 is sealingly connected with the hood inner plate 20 and is located below the drainage hole 209. The hood inner plate 20 further comprises a drainage hole 209, which is located below the radiator hole 101. The hood outer plate 10 comprises the radiator hole 101 and the radiator mesh cover 102 provided on the radiator hole 101. The radiator mesh cover 102 is used to block the external particulate matter. The drainage device 30 comprises an inlet 301 and an outlet 302, the inlet 301 is correspondingly provided with the drainage hole 209, and the outlet 302 extends to the outside of the front cabin. The outlet 302 of the present embodiment is provided in the fender support outside the front cabin. The fender support is provided outside the front cabin to drain the water outside the front cabin, which will not affect the components in the front cabin.

[0084] In Figure 2In the shown embodiment, the front hood 1 comprises at least one pair of water drainage devices 30, which are symmetrically distributed along the central axis of the inner panel 20 of the bonnet towards the two sides of the front engine compartment. By arranging at least one pair of water drainage devices and symmetrically distributing the pair of water drainage devices along the two sides of the front engine compartment, the required space is small and the water drainage path is short, which is conducive to water drainage.

[0085] The front hood 1 of the embodiment of the present application can drain away the water coming from the heat dissipation holes 101 of the outer panel 10 of the bonnet through the water drainage devices 30 arranged below the inner panel 20 of the bonnet, and can ensure that the water does not enter the engine compartment on the basis of ensuring that the inside of the engine compartment is in communication with the outside for heat dissipation, thereby meeting the requirement of waterproofing the engine compartment.

[0086] In Figures 8 to 10 In the shown embodiment, the water drainage device 30 comprises a water drainage groove 303 and a cover plate 304 arranged on the top of the water drainage groove 303. The cover plate 304 is arranged on the top of the water drainage groove 303. The cover plate 304 partially covers the top of the water drainage groove 303, and the water drainage groove 303 is partially exposed to form an inlet 301, so that the opening of the inlet 301 is upward and corresponds to the water drainage hole 209. The outlet 302 is arranged outside the front engine compartment and extends into the fender support of the front engine compartment. The outlet 302 is arranged in the fender support, and the fender support is provided with a water drainage channel, so that the water in the water drainage device 30 is drained out of the vehicle. In this way, on the basis of ensuring that the inside of the front engine compartment is in communication with the outside for heat dissipation, the water does not enter the front engine compartment, thereby meeting the requirement of waterproofing the engine compartment. Moreover, the water drainage device 30 formed by the water drainage groove 303 and the cover plate 304 has a simple structure, is easy to install, and has a low cost.

[0087] In Figures 8 to 10 In the shown embodiment, the water drainage groove 303 comprises a first water drainage end 305 and a second water drainage end 306 arranged oppositely, the first water drainage end 305 is arranged close to the inlet 301 relative to the second water drainage end 306, and the second water drainage end 306 is arranged close to the outlet 302 relative to the first water drainage end 305. That is, the first water drainage end 305 is located below the water drainage hole 209, and the second water drainage end 306 is located in the fender support. The bottom surface of the first water drainage end 305 is arranged to be higher than the bottom surface of the second water drainage end 306, which can increase the water potential in the water drainage groove 303 and accelerate the water flow speed, thereby being conducive to water drainage. In some embodiments, the height difference between the first water drainage end 305 and the second water drainage end 306 is at least 10 mm. The height difference between the first water drainage end 305 and the second water drainage end 306 can be 10 mm or more, which can increase the water potential in the water drainage groove 303 and accelerate the water flow speed, thereby being conducive to water drainage.

[0088] In some embodiments, the drainage groove 303 is partially located on the top of the shock absorber, and a first gap is provided between the bottom of the drainage groove 303 and the top of the shock absorber. The first gap here represents the electrical safety distance between the drainage groove 303 and the shock absorber. In some embodiments, the size of the first gap is set to be at least 3 mm. In some embodiments, the size of the first gap can be set to be 3 mm or more. In this way, a safety distance is provided between the drainage device 30 and the shock absorber, and the depth of the drainage groove 303 is maximized by utilizing the internal space of the front engine compartment, which can increase the drainage capacity of the drainage groove 303 and facilitate the drainage of more water. In some embodiments, the top surface of the drainage groove 303 is inclined, and the inclination angle is in the range of 10°-15°. In some embodiments, the inclination angle of the drainage groove 303 can be 10° or 12° or 14° or 15°. The inclination of the top surface of the drainage groove 303 facilitates drainage.

[0089] In some embodiments, a second gap is provided between the bottom of the drainage groove 303 and the top of the engine. The second gap here represents the electrical safety distance between the drainage groove 303 and the engine. In some embodiments, the size of the second gap is set to be at least 30 mm. In some embodiments, the size of the second gap can be set to be 30 mm or more. In this way, a safety distance is provided between the drainage device 30 and the engine, and the depth of the drainage groove 303 is maximized by utilizing the internal space of the front engine compartment, which can increase the drainage capacity of the drainage groove 303 and facilitate the drainage of more water. For the engine, the engine moves up and down when it is running, so the safety distance between the bottom of the drainage groove 303 and the top of the engine is set to be larger, which does not affect the vibration of the engine and sets the depth of the drainage groove 303 in the limited space. The depth of the drainage groove 303 is not limited in particular and can be set according to the actual space in the front engine compartment.

[0090] In Figures 8 to 10 In the illustrated embodiment, the drainage device 30 includes a sealing member, which includes a first sealing member 307 and a second sealing member 308. The first sealing member 307 is arranged between the drainage groove 303 and the cover plate 304, and the second sealing member 308 is arranged between the inlet 301 and the inner panel 20 of the hood. The first sealing member 307 is used to seal the drainage groove 303 and the cover plate 304, and the second sealing member 308 is used to seal the inlet 301 and the inner panel 20 of the hood, which improves the sealing performance and enhances the waterproof effect. The first sealing member 307 and the second sealing member 308 can be made of sealing foam, which is compressible, has good sealing performance, and is light in weight. When the front hood 1 is closed, the foam on the drainage device 30 forms a seal at the contact position with the inner panel 2010, preventing water from entering the engine compartment.

[0091] InFigures 2 to 6 In the illustrated embodiment, the hood inner panel 20 is concave from top to bottom to form a drainage well 210. The drainage hole 209 is provided in the drainage well 210, and the drainage device 30 is assembled at the bottom of the drainage well 210 and is arranged correspondingly with the drainage hole 209. The drainage hole 209 is arranged vertically through, and the drainage device 30 is assembled in the drainage well 210. The external water first passes through the heat dissipation hole 101 and then enters the drainage device 30 through the drainage well 210. The drainage well 210 plays a guiding role. The hood inner panel 20 is provided with the drainage well 210, and the drainage device 30 is arranged at the bottom of the drainage well 210, which is conducive to drainage. The hood inner panel 20 is provided with the drainage well 210, which is conducive to the installation of the drainage device 30 on the one hand and the drainage on the other hand.

[0092] In Figures 2 to 6 In the illustrated embodiment, the front hood 1 further comprises a water baffle 40, which is arranged at the upper edge of the drainage well 210 and partially extends above the drainage well 210. The water baffle 40 is arranged at the upper edge of the drainage well 210 to prevent water from splashing to other positions of the hood inner panel 20, thereby improving the waterproof effect. In some embodiments, the water baffle 40 is located between the heat dissipation hole 101 and the plurality of air guide holes 201 in the direction from the inner panel rear end 20B to the inner panel front end 20A. Arranging the water baffle 40 between the heat dissipation hole 101 and the plurality of air guide holes 201 can block water from entering the front engine compartment, thereby improving the waterproof effect.

[0093] In some embodiments, the drainage well 210 comprises a well bottom surface 211 and first and second well side surfaces 212 and 213 arranged on both sides of the well bottom surface 211. The first and second well side surfaces 212 and 213 are arranged oppositely inclined to the well bottom surface 211. The drainage hole 209 is arranged in the well bottom surface 211. The drainage device 30 is arranged at the bottom of the drainage well 210. The first well side surface 212 is connected to the hood outer panel 10, and the upper edge of the first well side surface 212 is sealingly connected to the hood outer panel 10, which can be referred to as the first connecting flange 205. There is a gap between the second well side surface 213 and the hood outer panel 10, which is reserved for discharging hot air in the front engine compartment, that is, the gap can be a communication gap between the heat dissipation channel and the heat dissipation hole 101. The water baffle 40 is arranged at the upper edge of the second well side surface 213 and extends towards the side of the drainage hole 209. The water baffle 40 is arranged to prevent water from splashing to the hood inner panel 20, thereby avoiding water from splashing into the front engine compartment and improving the waterproof effect.

[0094] In Figures 2 to 6In the shown embodiment, the water drainage sink 210 is provided with a guide flange 214 arranged at the inner edge of the water drainage hole 209. The guide flange 214 is used to guide the water flow into the water drainage groove 303. The guide flange 214 extends from the inner edge of the water drainage hole 209 upwardly and partially into the water drainage device 30. The arrangement of the guide flange 214 at the inner edge of the water drainage hole 209 is conducive to guiding the water into the water drainage device 30 and facilitating water drainage. In the present embodiment, the connection between the guide flange 214 and the water drainage hole 209 is arc-shaped and chamfered, which is good for splash-proof effect and conducive to guiding the water into the water drainage groove 303.

[0095] In Figures 2 to 6 In the shown embodiment, the water baffle 40 is inclined upwardly at the portion extending outwardly from the second sink side surface 213. The inclined arrangement of the water baffle 40 at the outwardly extending portion is conducive to water blocking and improving the water-proof effect. In some embodiments, the size of the water baffle 40 extending outwardly from the second sink side surface 213 is at least 10 mm. That is, the distance of the water baffle 40 extending outwardly from the second sink side surface 213 can be set to 10 mm or more. The size of the water baffle 40 extending outwardly is at least 10 mm, which is better for water blocking. In some embodiments, the material of the water baffle 40 is carbon fiber. The water baffle 40 is bonded to the inner hood panel 20 by epoxy structural adhesive. The carbon fiber material can meet the energy saving requirement by balancing the light weight and strength. In some embodiments, the heat dissipation hole 101 is concave from top to bottom. The highest point of the outer edge of the water baffle 40 is at least higher than the height of the heat dissipation hole 101. The arrangement of the highest point of the outer edge of the water baffle 40 being higher than the heat dissipation hole 101 is conducive to blocking the water from entering the inner hood panel 20 and is good for water blocking. In some embodiments, the area of the hood outer panel 10 provided with the heat dissipation hole 101 is inclined from the inner panel rear end 20B to the inner panel front end 20A and partially embedded in the area of the water drainage sink 210. That is, the hood outer panel 10 is inclined from top to bottom and partially located in the area of the water drainage sink 210 in the vertical direction. The downwardly inclined arrangement of the area of the hood outer panel 10 provided with the heat dissipation hole 101 is conducive to draining the external water into the water drainage hole 209 of the water drainage sink 210 and facilitating water drainage.

[0096] In Figures 8 to 10In the shown embodiment, the front engine compartment is provided with a plurality of component mounting positions, two of which include a fender mounting position for mounting a fender and a ventilation cover mounting position for mounting a ventilation cover. The drainage device 30 includes a plurality of device mounting positions, one of which S1 is shared with the fender mounting position, one of which S2 is shared with the ventilation cover mounting position, and the other S3 is mounted by a welded mounting bracket. The fender mounting position and the ventilation cover mounting position are distributed on both sides of the drainage device 30. The device mounting position of the welded mounting bracket is located in the middle region of the drainage device 30. In this way, the drainage device 30 is mounted using the plurality of mounting positions provided in the front engine compartment, reducing the number of mounting components and the difficulty and cost of installation.

[0097] In the above scheme, the water flow entering through the heat dissipation hole 101 of the hood outer plate 10 is guided to the fender support position outside the engine compartment by the drainage device 30 across the guide flange 214, and the upper part of the drainage device 30 is provided with sealing foam. When the front hood 1 is closed, the sealing surface of the hood inner plate 20 interferes with the foam, thereby ensuring that the water in the drainage device 30 does not enter the interior of the front engine compartment, and the water flow impacting the hood inner plate 20 is blocked by the water baffle 40 bonded to the hood inner plate 20 and falls into the drainage device 30 for drainage. When the gas in the front engine compartment is connected to the outside, water flow does not enter the front engine compartment.

[0098] The present application proposes a brand new front hood 1, which can maintain the appearance and meet the requirements of thermal management, water management, aerodynamics and other needs without changing the engine compartment structure of traditional vehicles. At the same time, the cost is controlled within a lower range. On the basis of meeting the technical requirements, the three core advantages are realized simultaneously: first, to ensure the efficient operation of the heat dissipation and ventilation function, second, to ensure the excellent waterproof sealing of the engine compartment opening, and third, to break through the industry bottleneck in design structure. This scheme can make the engine front-mounted mass-produced vehicles not only realize heat dissipation through real openings, but also completely eliminate the design of false openings, avoid the risk of water entering the engine compartment, and at the same time, get rid of the limitations of no guarantee after modification. It has the visual sense of sports, design innovation and use safety.
